基于LTE-A上行CoMP物理层接收技术的研究(任务书,开题报告,论文15000字)
摘 要
为满足未来的无线通信市场的更高需求与更多应用，3GPP（the 3rd Generation Partnership Project）提出了LTE的演进版本：LTE-Advanced。
    在LTE-Advanced中，引入了很多关键技术来提升整个通信系统的性能，如中继（Relay）技术，OFDM技术，多点协作技术（CoMP）等等，这些技术主要目的是为了消除小区间干扰，提高小区边缘用户吞吐率。其中CoMP技术作为一门新兴技术发挥尤为重要的作用，它是通过多个小区之间的协作，为若干用户进行服务，主要目的是增大小区边缘用户吞吐量，提高整个系统服务质量。
本文首先简要介绍了LTE-A的研究背景和关键技术等，然后详细介绍了CoMP技术的分类、基本概念等。通过查找资料，学习CoMP协作点选择算法，资源调度算法，了解CoMP具体是怎么选择用户形成协作集的，最后介绍一种重要的CoMP上行接收技术：上行联合均衡接收。最后通过MATLAB进行仿真，来证明CoMP技术确实可有效提升边缘用户的吞吐量、信道容量等相关性能。

Abstract
    To meet the higher demand for more applications and future wireless communications market, 3GPP (the 3rd Generation Partnership Project) presented an evolved version of LTE: LTE-Advanced.

In LTE-Advanced, the introduction of a number of key technologies to improve the performance of the entire communication system, such as a relay (Relay) technology, OFDM technology, multi-point collaboration technology (CoMP), and so on, these techniques primarily to eliminate inter-cell interference improve cell edge user throughput. Wherein CoMP technique is introduced as a new technique, it is through collaboration among a plurality of cells, a number of service users, the main purpose is to increase the cell edge user throughput, improve overall system quality of service.
    This paper briefly introduces the research background and key technologies of LTE-A , and then details the CoMP classification, the basic concepts. By looking for information, learning CoMP coordination point selection algorithm, resource scheduling algorithm, understanding CoMP specifically how to select a user sets formed collaboration, Finally, an important CoMP uplink reception technology: Joint equilibrium uplink reception. Finally, MATLAB simulations to prove CoMP technology really can effectively enhance the edge user throughput, channel capacity and other properties. [资料来源：http://Doc163.com]
